The inclined wedge is made of steel or iron material.

The inclined wedge is made of steel or iron material.

A slidable wedge block is supported for reciprocal movement on the angled surface.

An angled interface between the cleat and receptacle provide a friction fit engagement to minimize inadvertent disengagement of the cleat and receptacle.

The wedge piece is vertically-movable and has a face abutting the slanted face of the retaining piece.

The inclined wheel is inclined towards outer side.

The ramped tip may comprise a first ramped surface and a second ramped surface, the second ramped surface may align with the ramped surface of the distal end of the marker exit.

The first slanted tongue (11) and the first slanted groove (12) respectively match the second slanted tongue (13) and the second slanted groove (14).

Formed continuously in each inclined part are a steeply inclined part and a gently inclined part having a gentler slope than the steeply inclined part.

A stationary shaft is supported generally parallel to the angled surface of the backing wedge block with a stationary piston secured to the shaft at an end.

An inclined groove (11) has a first inclined groove (101) and a second inclined groove (102).

The second member includes an annular ramped portion (62), which is complementary to the annular ramped surface (40), in abutting relationship to the ramped surface.

The inclined region (6T1) has at least one inclined face that is inclined with respect to the face of the inclined region (6T1) side of the signal wirings (5by).

This rim tilts from a non-inclined position to an inclined position.

Each of the grooves has a first inclined surface and a second inclined surface.
